What is the AC Unit in the Attic Called?
An air conditioning unit located in your attic is most commonly called an attic air handler or an attic air conditioner. However, the precise terminology can be a bit nuanced depending on the specific setup. Let's delve into the details.
What's the difference between an attic air handler and an attic air conditioner?
This is where things get slightly confusing. The terms are often used interchangeably, but there's a subtle distinction:
-
Attic Air Handler: This term usually refers to the indoor unit of a split-system air conditioner. The air handler itself doesn't contain the refrigerant or the compressor; these are located in a separate outdoor unit (the condenser). The attic air handler simply circulates conditioned air throughout your home. It contains the blower motor, evaporator coil, and air filters.
-
Attic Air Conditioner: This term is sometimes used to describe a complete, self-contained air conditioning unit located in the attic. In this case, the unit houses both the evaporator coil and the compressor, meaning it doesn't require an external condenser. These are less common than split systems but are still found in some homes, particularly older ones.
Therefore, simply calling it an "attic AC unit" is perfectly acceptable and generally understood.
What are the other names people use for an attic AC unit?
While less common, you might also hear it called:
- Upflow air handler: If the air is blown upwards from the unit.
- Downflow air handler: If the air is blown downwards from the unit. This is more common in attic installations.
- HVAC unit in the attic: This is a broader term encompassing both the heating and cooling components if your system includes both.
Why is my AC unit in the attic?
Placing the air handler in the attic is a common practice for several reasons:
- Space saving: It keeps the bulky unit out of valuable living space.
- Airflow efficiency: The attic can provide sufficient airflow for efficient cooling.
- Noise reduction: The noise generated by the blower is less disruptive when located away from living areas.
However, there are also potential drawbacks, such as increased heat load in hot climates and accessibility challenges for maintenance.
How do I know what type of AC unit I have in my attic?
The best way to identify your specific unit is to:
- Visually inspect the unit: Look for model numbers and labels on the unit itself. This information will provide clues about the type of unit and its capabilities.
- Consult your HVAC system documentation: Your system's manuals should provide detailed information about its components.
- Contact an HVAC professional: If you're unsure, a qualified technician can readily identify the type of air conditioning unit in your attic.
Understanding the specifics of your attic AC unit will help you troubleshoot problems, schedule maintenance, and make informed decisions regarding future upgrades or replacements.
